The 2015 course has been certified by USATF and a downloadable course map has been posted on the race website at

Detours have been taken into consideration in the certification of the course. The 1st detour between Florida Avenue (~M9) on the south and Exposition Avenue (~M10) on the north will remain in place during the race.

The 2nd detour between Bayaud Avenue (~11M) on the south and 8th Avenue (~12M) on the north will be removed on Sunday to accommodate the runners.

Platte River Half Marathon and Buckhorn Exchange Relay runners will be the 1st users of this new stretch along the Trail! Thanks to Denver Parks and Rec and Kraemer North America for diligently working to complete this section of the Trail prior to the race.

We are looking forward to see you on a perfect day for running!
